The development and testing of recipes for patients with chronic renal failureConradie, Nelene 03 1900 (has links)
Thesis (MNutr (Human Nutrition))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Background
Patients with chronic renal failure must deal not only with the disease itself, but also have to
follow a strict dietary regimen. In South Africa there is currently a great demand for new and
updated recipes based on the South African Renal Exchange Lists. The focus of this
research was the development and testing of recipes commonly used by renal patients
following a westernised diet.
Objectives
The main objectives of the study were to develop and test recipes that meet the nutritional
requirements of patients with chronic renal failure. The secondary objectives were to
determine the gender and racial differences in participants’ responses during consumer
sensory testing.
Methodology
The study population consisted of patients with chronic renal failure on hemodialysis and
continuous ambulatory peritoneal dialysis from Tygerberg Academic Hospital (TAH). Data
was collected in three phases, using census sampling: Phase 1 included the development
and adaptation of recipes to suit the renal diet. Phase 2 included the consumer sensory
testing of the recipes by the dialysis patients, using the 9-point hedonic scale. Phase 3
included the rating of the recipes, the final nutritional analysis and allocation of renal
exchanges to one portion of each recipe, as well as the final formatting of the recipe to make
it more user-friendly for the renal patient.
Results
In total, 45 patients took part in the sensory evaluation of 30 recipes. Eighty percent of the
subjects were coloured, 4% were white while 16% were black. Fifty-one percent (n=23) were
female and 49% (n=22) were male. Of the 30 recipes that were evaluated for overall
acceptance, appearance, smell, texture and taste, only 7 were deemed unacceptable.
Recipes were unacceptable when less than 80% of the study participants gave a mean
overall score of more than 6. Significant differences in the overall acceptability scores were
found between the male and female subgroups for the Fish and Vegetable Pie (p=0.031),
Chicken Pilaf (p=0.008) and Date Fingers (p=0.002). The females showed a greater
preference for these two main meals while the males showed a greater preference for the
Date Fingers. Significant differences were found between the black and westernised
subgroups for the Rice Salad (p=0.006), Wheat and Mushroom Casserole (p=0.022), Curried
Wheat Salad (p=0.043) and the Coconut Ice (p=0.005), with the westernised subgroup
showing a greater preference for the dishes than the black subgroup. Conclusion
The 23 recipes that were acceptable to the study participants are recommended for inclusion
in the RenalSmart Software programme. These recipes are suitable for patients following a
westernised diet. It is proposed that recipes suitable for the black and Indian population must
be developed in future research. / AFRIKAANSE OPSOMMING: Agtergrond
Pasiënte met chroniese nierversaking moet nie net slegs die siektetoestand hanteer nie,
maar moet ook ‘n streng dieet regime volg. Daar is huidiglik in Suid-Afrika ‘n groot behoefte
vir nuwe en opgedateerde resepte gebasseer op die Suid-Afrikaanse Nier Ruillyste. Die
fokus van hierdie navorsing was om resepte te ontwikkel en te toets wat algemeen ingeneem
word deur nierversaking pasiënte wat ‘n westerse dieet volg.
Doelwitte
Die hoof doelwitte van die studie was om resepte te identifiseer en te toets wat voldoen aan
die nutrisionele behoeftes van nierpasiënte met kroniese nierversaking. Die sekondêre
doelwitte was om geslag en ras verskille in die deelnemers se reaksies tydens verbruiker
sensoriese evaluering te bepaal.
Metodologie
Die studie populasie het bestaan uit pasiënte met chroniese nierversaking op hemodialise en
aaneenlopende ambulatoriese peritoneale dialise van Tygerberg Akademiese Hospitaal
(TAH). Data was versamel in drie fases deur gebruik te maak van sensus steekproeftrekking:
Fase 1 het die ontwikkeling en aanpassings van die resepte, om dit toepaslik te maak vir die
nier dieet, ingesluit. Fase 2 het die verbruiker sensoriese evaluering van die resepte deur die
dialise pasiënte, met behulp van die 9-punt hedoniese skaal, ingesluit. Fase 3 het die
klassifisering van die resepte, die finale nutrisionele analise en die toekenning van nier ruile
per porsie van elke resep, sowel as die finale formatering om die resep meer gebruikersvriendelik
te maak vir die nierpasiënt, ingesluit.
Resultate
In totaal het 45 pasiënte aan die sensoriese evaluering van die 30 resepte deelgeneem.
Tagtig persent van die deelnemers was kleurling, 4% was wit en 16% was swart. Een en
vyftig persent (n=23) was vroulik en 49% (n=22) was manlik. Van die 30 resepte wat geevalueer
is vir algehele aanvaarding, voorkoms, reuk, tekstuur en smaak, was slegs 7
onaanvaarbaar gevind. Resepte is as onaanvaarbaar beskou indien minder as 80% van die
deelnemers ‘n gemiddelde algehele telling van meer as 6 gegee het. Beduidende verskille in
die algehele aanvaarbaarheid tellings is gevind tussen die mans en vroue vir die Vis en
Groente Pastei (p=0.031), Hoender Pilaf (p=0.008) en Dadelvingers (p=0.002). Die vrouens
het ‘n groter voorkeur vir die twee hoofgeregte getoon terwyl die mans ‘n groter voorkeur vir
die Dadelvingers getoon het. Beduidende verskille is gevind tussen die swart en westerse
sub-groepe vir die Rysslaai (p=0.006), Koring en Sampioen Kasserol (o=0.022), Kerrie
Koringslaai (p=0.043) en die Klapperys (p=0.005), met die westerse sub-groep wat ‘n groter
voorkeur vir dié geregte toon as die swartes. Gevolgtrekking
Die 23 resepte wat aanvaarbaar gevind is sal voorgestel word om ingesluit te word in die
RenalSmart Sagteware program. Die resepte is toepaslik vir pasiënte wat ‘n westerse dieet
volg. Daar word voorgestel dat resepte toepaslik vir die swart en Indiër populasie ontwikkel
word in toekomstige navorsing.

Cultural practices and diet adherence of patients living on haemodialysisRamkelawan, Verosha 10 1900 (has links)
Text in English with abstracts in English and isiZulu / Poor adherence to their prescribed diet, medications and treatment contributes to increased mortality and morbidity in patients with end-stage renal disease. These patients must change their diet when receiving dialysis treatment, but cultural beliefs and practices can affect their adherence to the prescribed diet.
The purpose of this qualitative, descriptive, exploratory study was to improve health education on prescribed diet adherence to patients living on haemodialysis at a haemodialysis unit in eThekwini Municipality. Data from a sample of 20 patients was collected using semi-structured interviews and analysed using qualitative content analysis.
The findings revealed that haemodialysis patients’ prescribed diet adherence was influenced by cultural and religious views, and by family support. Food availability, patients’ geographical location and patients’ financial means hindered their adherence to their prescribed diet. A multi-disciplinary health care team including nurses, should be sensitive to patients’ different cultural beliefs and practices when providing health education. / Ukungabambeleli endleleni emisiwe yokudla, amakhambi nasekwelashweni kunomthelela ekwandiseni izimpawu zesifo sezinso esingapheli (ESRD) futhi kwandisa isibalo sabantu ababulawa yilesisifo. Iziguli ezinalesisifo zidinga ukushitsha indlela yokuphila, iziphuzo kanye nokulandela indlela emisiwe yokudla kakhulukazi mabe ngaphansi kokwelashwa ngokuhlanzwa kwegazi ngomshini (dialysis). Izinkolelo zamasiko nendlela zokuphila ezihambisana namasiko kwenze imfundiso nge ezempilo maqondana nendlela emisiwe yokudla yaba lukhuni.
Inhloso yalolucwaningo bekuwukwandisa ulwazi nemfundiso ngezempilo mayelana nokulandela indlela emisiwe yokudla kwiziguli izithola ukulashwa ngokuhlanzwa kwegazi ngomshini (haemodialysis) esikhungweni esikuMasipala weTheku.
Kusetshenziwe indlela yokwenza ucwaningo esezingeni elifanele, Imininingwano eqoqiwe eqembini (sample) leziguli ezingamashumi amabili (20) ezithola ukwelashwange haemodialyisis. Imininigwane iqoqwe kusetshenziswa izingxoxo ezihleliwe. Imigomo elawula ukuhlaziya ilandeliwe yonke ngenkathi kwenziwe lolucwaningo.
Lolucwaningo luveze ukuthi indlela yokudla emisiwe yeziguli ezikwi dialysis iphazanyiswa imobono yamasiko, inkolo kanye nokusekelwa nokuzimbandakanya kwamalungu omndeni. Izinselelo ezinjengokutholakala, indawo isiguli esihlala kuyo nezinkinga zemali zivimbela ukubambelela endleleni emisiwe yokudla. Abasebenzi bezempilo kumele banakekele indima edlalwa izinkolelo namasiko uma befundisa ngezempilo ezigulini eziphethwe izinso. / Nursing Science / M.A. (Nursing Science)
